Title: Low cost equipment for cleaning using liquefiable gases
Inventor: STANFORD THOMAS B
IPC: B01D11/00
Filed: 1994-08-16
Abstract: LOW COST EQUIPMENT FOR CLEANING    USING LIQUEFIABLE GASES                 ABSTRACT OF THE DISCLOSURE      Precision cleaning of parts (20)  is performed with liquefiable gases (12), such as CO2, without the use of a complex and costly processor system.  Rather, simplified and reliable performance for small scale and "low end" cleaning applications is accomplished without the use of pumps and condensers.   The apparatus  (10)  for removing undesired material from a chosen substrate comprises: (a) an enclosed cleaning chamber (17) in a walled vessel (10) for containing a liquid (12') derived from the liquefiable gas and the substrate containing the undesired particulates and contaminants the walled vessel adapted to withstand a maximum pressure of about 1,500 pounds per square inch (105.4 kg/cm2) at ambient temperature; (b) means (21) for supporting the substrate  in the cleaning chamber;  (c) ultrasonic energy-producing transducer means (18) attached to the walled vessel within the cleaning chamber; (d) inlet means (16) attached to the walled vessel for introducing the liquiefiable gas into the cleaning chamber under a pressure less than about 900 pounds per square inch (63.3 kg/cm2); (e) temperature control means (27) connected to the cleaning chamber for controlling the temperature within the chamber up to about 50°C; (f) reservoir means (14, 44) for providing the liquefiable gas to the inlet means; (g) means for changing the liquefiable gas to the liquid; and (h) outlet means (22) in the chamber for removing the liquid from the cleaning chamber.  The liquid may then be further treated to remove particulates and organic contaminants and either recycled to the cleaning chamber or vented to the atmosphere.  The process is especially applicable for gen-eral degreasing and particulate removal processes, when high precision cleaning is not required.
Patent CA-2130527-A1 (CA)
Inventor: CORDSEN ANDREAS
IPC: G01V1/36
Filed: 1994-08-19
Abstract: The invention involves providing a plurality of substantially parallel and equally spaced source lines, each of which are formed by a plurality of equally spaced seismic energy sources. A plurality of substantially parallel and equally spaced receiver lines are also provided, each formed by a plurality of equally spaced seismic energy receivers. The source and receiver lines are overlaid in a transverse crossing manner, forming a rectangular grid, so that the spacing or relative offset between source and receiver is repeated only at every second or greater number of crossings. Preferably, the relative offset is substantially zero so that a source and a receiver are substantially coincident at only every second or greater number of crossings. For each seismic disturbance, an array of common mid-point ("CMP") seismic reflections is produced. Each CMP forms the center of one of multiple sub-bins which together form a standard bin. Stated otherwise, by slightly varying the source, receiver and line intervals so that the relative offset between a receiver and a source is repeated, but only at every second or greater crossing, the number of CMP's per bin has been multiplied. During processing of the seismic survey results, adjacent sub-bins can be incrementally combined or trimmed to adjust the standard bin to a larger or smaller size, thereby permitting an explorationist to optimize between increased fold or more detailed resolution respectively.
